Marine Pollution: Current Status, Impacts and Remedies
While oceans are vast, they represent a fragile resource that must be protected if we want to protect our livelihoods and our planet. Marine pollution has been a topic of concern for a long time, and it has recently attracted the attention of scientists, environmentalists, economists, politicians and journalists in mainstream media. Besides providing food, transportation routes and other resources, the oceans serve as a heat absorbing sink which offsets the extreme heating effects of climate change, but only to a limited degree. Pollution in marine environments such as the oceans, poses a threat to coastal communities by affecting the fauna and flora in the environment and the health of the ...
Advances in GIS and Remote Sensing the Landscape Pattern of Land Cover on Urban Climate and Urban Ecology
The rapid urban expansion and associated land cover conversions in the last two decades call for an urgent need for developing advanced analytical and quantitative methods to manage the adverse impacts on urban ecology and climate. The lower landscape connectivity, higher land cover fragmentation and increase in higher surface temperatures in urban areas are largely a consequence of surface energy balance alteration triggered by the replacement of natural land covers like green spaces, wetlands with built areas, and impervious surfaces. These spatial-temporal variability changes have detrimental and significant impacts on the local and regional urban climate challenges that require both new ...
Toxicological Assessment of Combined Chemicals in the Environment
Practitioners do not have an adequate understanding of how small changes in mixtures of chemicals will affect toxicity in an organism. The current belief is the mechanism of action must be known and similar for all chemical involved to be able to adequately predict mixture effects. This book provides a discussion of approaches, molecular mechanisms, and the challenges involved in the assessment of mixtures. In the first section of the book a brief introduction to the background and significance of combined toxicity is provided describing the degradation, oxidation, absorption, distribution, biotransformation and excretion of various compounds in the environment and organism. Section two intr...
The Geographical Sciences During 1986—2015
In four chapters and an introduction, this book systematically helps readers understand the development of the Geographical Sciences both in China and in the world during the past 30 years. Through data analysis of methodologies including CiteSpace, TDA, qualitative analysis, questionnaires, data mining and mathematical statistics, the book explains the evolution of research topics and their driving factors in the Geographical Sciences and its four branches, namely Physical Geography, Human Geography, Geographical Information Science and Environmental Geography. It also identifies the role of the Geographical Sciences in the analysis of strategic issues such as global change and terrestrial ...
Reservoir Ecotoxicology
Reservoir construction is the key strategy for water resource management. In recent years, the migration of pollutants and their transformation into the reservoir ecosystem has become a global problem. Intensified anthropogenic activities and unsustainable practices have amplified the pollutant levels in the reservoir. Therefore, this book intends to highlight environmental characteristics of the reservoir, study methods of ecotoxicology, and mechanistic toxicogenetic pathways of pollutants in the reservoir. Adverse outcome pathway (AOPs) model is used to elucidate toxicological effects of reservoir pollutants. Moreover, ecological and human health risks of the Three Gorges Reservoir (TGR), the largest power generation reservoir on earth, and its pollution status are also discussed.

Echinoderms: Munchen
Since 1972, scientists from all over the world working on fundamental questions of echinoderm biology and palaeontology have conferred every three years to exchange current views and results. The 11th International Echinoderm Conference held at the University of Munich, Germany, from 6-10 October 2003,continued this tradition. This volume comprises 95 submitted papers and 96 abstracts covering a wide spectrum from innovative student contributions to the lessons learnt from experienced specialists. The content of the contributions ranges from original research results to the latest synopses concerning a variety of topics, including visual sensing, larval cloning, mutable collagenous tissues, sea urchin aqua-culture, deuterostome phylogeny, palaeobiology and taphonomy.
Education and Society in Post-Mao China
The post-Mao period has witnessed rapid social and economic transformation in all walks of Chinese life – much of it fuelled by, or reflected in, changes to the country’s education system. This book analyses the development of that system since the abandonment of radical Maoism and the inauguration of ‘Reform and Opening’ in the late 1970s. The principal focus is on formal education in schools and conventional institutions of tertiary education, but there is also some discussion of preschools, vocational training, and learning in non-formal contexts. The book begins with a discussion of the historical and comparative context for evaluating China’s educational ‘achievements’, fo...
